The Yokogawa EY200 Digital Earth Tester is an earth resistance tester for testing power distribution lines, in-house wiring system, electrical appliances etc. The Yokogawa EY-200 also has an earth voltage range for earth voltage measurement.
A simplified 2-pole measuring method can be used if there is an almost perfectly earth/ground object such as a lead or iron water-pipe (plastic pipes cannot be used) or if there is an object with a known value of earth resistance, near the measurement site. The Yokogawa ey200 Digital Earth Tester is dust and drip resistant (IP54 rated).
